I just gave it a short try...
(dot)12_8_BALLAD still the same problem...
If you change from Var a to B ( or similar, with activated "AutoFill" ) the display shows "FILL1 >>" and doesnīt change.
Sometimes the drums were muted again.
I didnīt try any other style yet and Iīm not in the mood for that at present time...
KETRON, did you change anything but the NAME of the file ?
